Abstract: 2-(-Alkylidene substituted)-5,5-dimethyl--lactones have been synthesized in two steps. The stable phosphorane carboethoxy┬şmethyledene (-prenyl)-triphenylphosphorane is condensed with different carbonyl compounds to afford ,-unsaturated esters which are cyclised using PPA to give title compounds
